The SeaWinds Algorithm Theoretical Basis Document
Entry ID: 01-seawinds-99
Abstract: (Summary adapted from the SeaWinds ATBD pdf file and the Winds web site)
The purpose of the SeaWinds Algorithm Theoretical Basis Document
(ATBD) is to describe the theoretical bases for the major scientific
algorithms that will be used in processing the SeaWinds (SWS) data.
Satellite-borne radar scatterometers, such as "SeaWinds",
are the only remote sensing systems presently capable of providing
... accurate, frequent, high-resolution measurements of ocean
near-surface wind speed and direction in both clear-sky and cloudy
conditions. However, scatterometer measurements are highly indirect,
and significant processing is required to estimate near-surface
wind velocity from the backscattered power measured directly by the
Knowledge of wind velocity over the ocean is of critical importance
for understanding and predicting many oceanographic, meteorological,
and climate phenomena. Measurements of surface wind velocity can be
assimilated into regional and global numerical weather prediction
systems, thereby extending and improving our ability to predict future
weather patterns on many scales. The SeaWinds instrument on the
QuikSCAT satellite is a specialized microwave radar that measures
near-surface wind speed and direction under all weather and cloud
conditions over Earth's oceans.
